wrk2

wrk2 is a constant throughput, correct latency recording variant of wrk.
It is a modern HTTP benchmarking tool capable of generating significant load
when run on a single multi-core CPU.

Usage:

$ wrk2 -R10 -c1 -t1 -d10 https://api.example.com

The command above runs a 10 RPS workload for 10 seconds and prints a short report.

Using your custom script to load APIs:

$ wrk2 -R100 -c1 -t1 -d60 -s myscript.lua --latency https://api.example.com

The command above runs 100 RPS workload with custom logic described in myscript.lua for 60 seconds and prints a detailed latency report.
